IPC: E02F5/02
Filed: 1978-08-11
Abstract: PURPOSE: To facilitate drilling, by keeping a new hole at accurate positional relationship without damaging a hole previously drilled by inserting a guide shaft, which does not revolve, into the hole previously dfilled while drilling earch and sand by means of a drilling shaft.  
     CONSTITUTION: A guide shaft 2, which does not rotate, and a drilling shaft 3, which drills revolving, are mounted to a drilling machine 1. A guide plate 9 is installed to the guide shaft 2. The guide shaft 2, which does not revolve, is inserted into a hole 5 previously drilled while earth and sand are drilled by rotating the drilling shaft 3, and a new hole 5a is drilled. Positional relationship between the hole beforehand drilled and the new hole 5a becomes accurate because holes are drilled by means of the drilling shaft 3 while the guide shaft 2 enters into the hole 5 beforehand drilled at that time. Since the guide shaft 2 does not revolve, the hole 5 drilled is not damaged as compared to the case when the shaft 2 is rotated.
